Influence of morphology of poly(3, 4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) layer on performance of bulk heterojunction (BHJ) organic solar cells is analysed. Morphology depends on next technological factors: dispersity of PEDOT:PSS solution, substrate treatment, drying, PEDOT:PSS treatment. It is shown that samples with layer roughness less 10 nm have the best performance. Layer roughness was studied by atomic force microscopy (AFM).
